The object of my invention is to prov de an improved carbonator forcarbonating liquids with gas obtained from a standard carbon dioxidecontainer and to provide novel means for thoroughly carbonating theliquid while the receptacle is stationary. It is also my object toprovide, in comblnatron with the carbonator, an automatic relief valve.It is further an object of my lnvention to provide a carbonator ofnormal shape, including means for supporting the carbon dioxidecontainer inoperative 1nverted position; and to provide the novelcombination and arrangement of parts disclosed in the accompanying drawngs, in which Figure 1 is'a vertical section of my mvention;

Fig. 2 is a horizontal sectlon on line 2-2 ofFig.1;and

Fig. 3 is an enlarged detailed sectional view on line 33 of Fig. 1.

Like numerals indicate like parts 1n each of the several views.

Referring to the accompanying drawings, a standard carbon dioxidecontainer 1, having the usual valve hand wheel 3 and threaded nozzle 2,detachably engaging the threaded opening or passage 4: in base extension6, is supported in operative posltion by a suitable bracket 21 carriedby the llqllld container 7. Base extension 6 is provided with a channel5 terminating in an upright nozzle 8. The channel 9 in nozzle 8 opensinto a lateral discharge passage 10, the liquld carbon dioxide escapingthrough the restricted opening 11, as indicatedin Figs. 1 and 3.

Liquid container 7 is provlded with a detachable cap 16 in which ismounted a suitable relief or safety valve 17. The container has adischarge pipe 18 termn atmg 1n the spigot 20, the outflow of the liguidbeing regulated by the valve 19, which is manually operated.

In operation, the liquid carbon diox de from container 1 is released byhandwheel valve 3 and flows through passage 4 and channel 5 under fullpressure from container 1. The liquid carbon dioxide flows throughchannel 5 in base extension 6 and thence to passage 10 through nozzleand discharges through the restncted opemng 11 in a conical spray 12,thence pursuing a spiral upward course as indicated by the arrows 14. Asthe carbon dioxide is in liquid form when it passes through channel 5 tonozzle 8 and changes to a gas and snow as it leaves nozzle 8 throughopening 11 at 12, the latent heat of vaporization of the liquid carbondioxide is absorbed and refrigerates as well as carbonates the contentsof tank'7. The force of discharge from high pressure through channels 5and 10 and restricted opening 11 causes a whirling motion of thecontents of the carbonator; also charging the contents with a volume ofatomized bubbles of carbon dioxide. The carbon dioxide gas bubbles beingmuch lighter than the liquid in the carbonator will be driven to thecenter of rotation by centrifugal force acting on the heavier liquid andthereby etfect an upward flow of the carbon dioxide gas through centerof carbonator simultaneous with the circular or spinning motion of thecontents of the carbonator, which causes a downward flow as indicated byarrows 15.

The unrestricted passage through members 4, 5 and 10, permittingapproximately full pressure of container 1 to reach the restrlctedpassage 11, removes the tendency of freezing from the valve incontainer 1. and through this passage to the point of actual expansionof gases at restricted passage 11, or completely within the contents ofthe carbonator, thus giving the greatest refrigerating effect to thecontents of carbonator.

This circulating means starting at the bottom of carbonator' and pushingits central contents upward and the outeror exterior contents downwardsimultaneous with a whirling effect brings each individual portion orounce of water contained in the carbonator directly to the nozzle whereit receives its proportionate charging of carbon dioxide, eliminatingthe need of rocking, shaking or stirrin the contents of carbona tor toget it to a sorb the carbon dioxide.

Many charges of liquid in tank 7 will be carbonated from a slnglecontainer 1 of liquid carbon dioxide without removing it. Upon emptyingthe liquid in tank 7 after the last charge from container 1, the emptycontainer will be removed and replaced by a full one. No check valve,therefore, is needed in the passage 5.

I claim:

1. In a carbonator, the combination of a. carbonating circular tank forliquid, means for supporting a standard container of 1i uid carbondioxide in communication wit 1 the interior of the tank, and a nozzleextending up into the bottom of the tank but Spaced apart a substantialdistance from the .side wall thereof, said nozzle having a tangentiallydirected restricted opening, whereby the carbon dioxide will escape intothe liquid in the carbonating tank reverting to a gaseous state andtravelling in a direction .to produce a whirling motion and effect aextension having a channel extending therethrough, said channelterminating at its outer end in a threaded opening of suitable size toreceive the nozzle of a standard container of carbon dioxide, thechannel at its I inner end termmatmg in a nozzle extending into theinterior of the tank, nearthe bottom thereof, said nozzle having anabruptly refor the escape of carbonstricted openin dioxide partly 1n agaseous and partly in a solid state on pressure being released as itflows from the aforesaid channel through the restricted opening in theaforesaid nozzle into the bottom of the tank to efficiently andsimultaneouslfcharge and refrigerate the contents of the tank.

3. In a carbonator, the combination of a tank for liquid having a baseextension, said extension having a channel extending therethrough, saidchannel terminating at its outer end in a threaded opening of suitablesize to receive the nozzle of a standard container of carbontdioxideunder high pressure, the channel at its inner end terminating in anozzle in the tank near the bottom thereof, said nozzle having arestricted opening, the nozzle being positioned at one side of the tankand near but substantially spaced away from and directed approximatelyparallel with the adjacent wall of the tank to allow the carbon dioxideto produce a swirling motion of the contents of the tank containing theliquid to be carbonated.
